const FancyButton = React.forwardRef((props, ref) => (
  <button ref={ref} className="FancyButton">
    {props.children}
  </button>
));

// You can now get a ref directly to the DOM button:
const ref = React.createRef();
<FancyButton ref={ref}>Click me!</FancyButton>;

what is forwardref in react ?

In React, parent components typically use props to transfer data down to their children. 
Consider you make a child component with a new set of props to change its behavior. 
We need a way to change the behavior of a child component without having to look for 
the state or re-rendering the component. We can do this by using refs. 
We can access a DOM node that is represented by an element using refs.
As a result, we will make changes to it without affecting its state or having to re-render it.

When a child component needs to refer to its parent’s current node, the parent component 
must have a way for the child to receive its ref. The technique is known as ref forwarding.

Syntax:

React.forwardRef((props, ref) => {})
